What this Trial Is About
Researchers are evaluating how anxiety traits affect pain, anxiety levels, and satisfaction with anesthesia in patients undergoing cataract surgery using topical anesthesia. The study explores the use of oral anti-anxiety medication, Xanax, compared to a placebo to improve comfort during this common surgery. The aim is to better understand how anxiety and sedation impact the surgical experience and patient satisfaction. Participants will be randomly assigned in a double-blind manner to receive either Xanax or a placebo 30 minutes before their cataract surgery. Anxiety levels will be assessed using the Beck Anxiety Inventory (BAI) and the State-Trait Anxiety Inventory (STAI) questionnaires before and after medication, as well as following surgery. The study focuses on cataract surgery performed with phacoemulsification and intraocular lens implantation under topical anesthesia. During the study, patients will complete anxiety questionnaires at recruitment, before surgery, and after surgery. Pain levels and satisfaction with anesthesia will be measured on the day of surgery and the following day. Researchers will monitor surgical procedures and anesthesia effects closely. The study lasts from recruitment through postoperative follow-up, including assessments up to 1 to 3 months after surgery to analyze anxiety and satisfaction outcomes.
